The
normative BIG5 model (a.k.a. Big Five, FFI, FFM, Five Factor
Model, OCEAN model) to measure personality of daters had been
proven/revealed as an incomplete and incorrect model to measure
personality of persons. Now it was replaced by HEXACO test, a.k.a Big
Six test. TheBIG5 normative personality testis the biggest mistake Psychologists
made since several years ago. The BIG5 is also known as the Five Factor
Model theory of personality traits, a psychological model based on
research by Paul Costa and Robert McCrae.

".. the Big Five's Agreeableness and HEXACO's
Agreeableness are not identical. The Big Five factors do not include an
Honesty-Humility factor, but some of the characteristics belonging to
Honesty-Humility are incorporated into the Big Five's Agreeableness
factor. Although earlier
investigations found only the Big Five factors, more recent studies
conducted in various languages (including English) with larger sets of adjectives recovered six factors. "

Many C-level executives (Management Teams of
several online dating sites) are cooking barbecues under the water
(selling smoke) and not paying attention to latest research from
Academics which could be beneficial for the Online Dating Industry.I think, legally, online dating sites using the Big Five model of personality could
be considered a FRAUD because they are using an incomplete model of
personality. They are assessing 5 scales and not 6 scales.
